Greetings from Oregon, USA!
Anyone I know who has used it over here loves it. I saw a few at the conference. There is a smaller version for those with smaller houses. A guy I know uses it now, but before he was in a wheelchair, so he is now independently mobile.
The reverse brake system is great and is regarded as one of the best features.
There is a laser option, although you have to be looking down to see it, and the guy I mentioned above tended to look straight ahead.
They are not cheap. Last time I looked they were over US$500, and the laser option was more than another $200.
I believe at least one guy at the conference rented one ( had PD + leg operation) so was using it for his convalescence.
Hope that helps!
